Serta vs Sam's.

I ordered a FULL SIZE topper. So far, I've received TWO TWIN SIZE TOPPERS and a THIRD is on the way! Sams says Serta is responsible, Serta says Sam's is responsible. What a WASTE OF MY TIME!

Sleeping better

I have been using this now for about 3 weeks. I needed to replace my old topper as it slid around too much at night and the plush topping part of the topper was bunching up. I love that it has the "fitted sheet" that holds the topper in place.
